Abstract: A processing method for radar signal with dual pulse repetition frequency, comprising: generating a first transmission signal and a second transmission signal, and perform a transmission process; reflecting a first echo signal and a second echo signal from an object, and converting the first transmission signal and the second transmission signal to a frequency domain information by using 2D (Two Dimension) fast Fourier transform (FFT); and filtering noise in the frequency domain information, and performing a calculation program by using a algorithm to obtain Doppler shift of the object. Thereby, the processing method of the present invention can overcome the bad operation ability of the lower hardware and advance the radar target detection speed restrictions.
